Claim 1
Independent Claim
194 words
A doll comprising a hollow torso, a head with mouth opening and a torso opening, a reservoir in said torso, means adapted to carry liquid from said mouth opening to said reservoir in said hollow torso and for equalizing pressure in said reservoir with atmosphere; means enabling the release of said liquid from said reservoir comprising an orifice in the wall of said reservoir and valve means mounted at said orifice to open and close said orifice to control the liquid flow therethrough to remain in a normally closed position; means for opening said valve including a lever having first and second ends, and being pivoted for displacing said first end thereof which is in mutual cooperative association with said valve means, means for creating magnetic attraction supported at said second end of said lever, and means disposed externally of said doll adapted to exert a magnetic force on said attraction means attached to said lever so as to pivot said lever and thereby enable the first end of said lever to act on said valve means and overcome said biasing means, whereby said liquid is released from said reservoir to said torso opening.
